Abstract: 1,258,192. Electrophotographic materials. INTERNATIONAL BUSINESS MACHINES CORP. 5 March, 1969 [25 March, 1968], No. 11658/69. Heading H1K. [Also in Division C7] A re-usable electrophotographic plate comprises a thin dielectric layer e.g. from 50- 4000  thick sputtered on to -the photoconductive insulating layer at such a temperature that deterioration of the photoconductive properties is avoided. A compressive stress which tends to increase the wear resistance of the layer can be imparted by maintaining the input power to the sputtering apparatus at a low level. RF sputtering is used if the target consists of the dielectric itself. Alternatively D.C. sputtering is effected in a reactive gas e.g. nitrogen, or oxygen to deposit compounds of an elemental target material. The preferred dielectrics are silica, titania, alumina, borosilicate glass, silicon carbide and nitride, and other oxides, carbides, borides and nitrides of elemental metals and alloys. Details of suitable sputtering apparatus and processes are given. The photoconductive layer, disposed on a conductive support, may consist of selenium various specified organic materials with or without a binder or A II B VI  compounds either in sintered form or dispersed in a thermoplastic resin or glass binder. In a specific example a tape of polyethylene terephthalate bearing a layer having a composition of one mole of 2,4-7 trinitro-9 fluorenone per mole of monomeric unit of poly- N-vinylcarbazole has its reverse side coated with silicone grease or other heat transfer medium and is then disposed on a water-cooled anode. By this means it is held at 50 C. while silica is sputtered on the photoconductive layer to a depth of 3000  from a silica target.

Abstract: 1,266,198. Three-dimensional linear interpolation. STARKSTROM-ANLAGENBAU KARL MARX - STADT - VEB. 25 April, 1969, No. 21267/69. Heading G4A. A method and apparatus for linear interpolation calculations in three or fewer dimensions for controlling the movement of a workpiece or an operative part of a machine is disclosed. Three co-ordinate values X, Y, Z are entered in respective stores SX, SY, SZ and their sum calculated in a register #S. A comparator AP calculates the largest co-ordinate, for example X, and sends a signal a which activates the XY plane sign store V 1  as minus and the XZ sign store V 2  as plus. These two stores activate a sign selection circuit VA which causes interpolation by one step in the X direction. Then the adders #1, #2, #3 and difference registers SD1, SD2, SD3 are operated on using the following table: As interpolation has just, occurred in the X direction, Y is added to register SD1 and Z subtracted from register SD2. Had the last interpolation occurred in the Y direction, X would have been subtracted from register SD1 and Z added to register SD3. The values of the registers cause the stores V 1 , V 2 , V 3  to give plus or minus signals to cause the next interpolation step via circuit VA. Circuit VA responds as follows: If the interpolation is in only one or two planes the appropriate stores have constant signs. Depending on the signs, another interpolation in one direction is carried out and the cycle repeated until all the registers and a counter are zero when the method is complete.

Abstract: 1,266,239. Digital data transfer. MARCONI CO. Ltd. 10 April, 1970 [20 June, 1969], No. 31341/69. Headings G4A and G4C. A digital data processor and store acts as an interface between a synchronous bit signal arrangement i.e. an arrangement which may perform any particular function only at the instant of certain predetermined clock pulses and an asynchronous bit signal arrangement i.e. an arrangement which, whilst being synchronized by clock pulses, may perform any particular function at the instant of any clock pulse. One preferred application is as an interface between a synchronous T.D.M. telephone circuit and as a synchronous central executive processor. Transfers from synchronous to asynchronous.- Digital signals from the synchronous arrangement arrive on line 4, pass through input/output register 5 and serial to parallel/parallel to serial converter 7 to a 32-channel cyclic store 6 where they build up. At regular intervals a central processor 11 is interrupted for a period by a controller 18 and the signals in store 6 are transferred in a block to a 32-channel first area 9 of a store 10, the area having toggles 27 which indicate whether a channel holds a signal and also the priority and destination of the stored signals. If the signals are for transfer to the asynchronous arrangement the scanner 19 informs the controller 18 which in turn informs the asynchronous arrangement. If the asynchronous arrangement can receive the signals, a command signal on lines 1 and 20 causes the signals in store 9 to be sent there via converter 15 and line 2. In one embodiment the unit 11 (having a read only programme store 12) processes the data before sending it on. In another embodiment the data is sent back to the asynchronous arrangement via line 3 e.g. for signals relating to initiation of a dial tone. Asynchronous to synchronous transfer.-Digital data is received via line 1 and converter 15 and sent to a second store area 14. The controller 18 is informed, detects the destination from the addresses found in area 14, transfers the data to channels in first area 9, then to a channel in store 6 when one is free, then via register 3 to the synchronous arrangement.
